Analysis of the Flow Pattern and Flow Rectification Measures of the Side-Intake Forebay in a Multi-Unit Pumping Station

To improve the problem of turbulence in forebay lateral inlet pumping station, a typical station project Xuzhou, Jiangsu Province, China was taken as research object. The is building connecting river channel and into water tank. Based on Reynolds-averaged Navier-Stokes (RANS) law k-? model, computational fluid dynamics method (CFD) technology compares analyzes numerical simulation with or without rectification measures for intake when multiple units are operating. three-dimensional model created by SolidWorks modeling software simulated CFX-ANSYS. alter flow pattern various were chosen. Internal patterns under plans, uniformity velocity distribution measuring section, vortex area reduction rates investigated compared. analysis comparison results, parabolic wall some piers set significantly it improves station. It also makes pool better increases 8%. Further, reduced 70%, effectively improving operating efficiency pump. results this paper provide technical reference improvement
